The Spoke Calculator is a precision tool I developed to help mechanics and hobbyists build bicycle wheels. Because wheel building tolerances are extremely tight (±1mm), accurate calculation is critical.
Features#
- Visual Lacing: Unlike spreadsheet calculators, this tool renders a real-time vector graphic of the wheel using the JSGL library.
- Dynamic Calculation: Users inputs rim diameter, hub flange dimensions, and spoke count to get instant length requirements.
- Pattern Verification: It allows users to visualize different cross-patterns (1-cross, 3-cross) to ensure physical compatibility with the hub.
Tech Stack#
- Frontend: HTML5, CSS3, JavaScript
- Vector Graphics: JSGL Library
- Backend logic: PHP (legacy support)
